No Signal - Android Q&A, Help & Troubleshooting

Hi Guys.
I have installed a new ROM on my phone (Asced G300), the PAC ROM....sometimes it disconnectfrom the network and the no service message appaear and i can not establish a connection with the network until i reboot the phone.
Is this a bug of this ROM or i am missing some setting? This is the 5th time that i am installing a ROM and i`m very tired of this game...

Could be a bug of the rom. I know it's probably difficult to get stable non stock based roms for your phone. You might want to check with the developers of the rom to see if there's preferred settings or another modem to use that might work better with it.

[Q] 3G/HSDPA Not working on Custom ROMs

Hi guys, faced a really weird issue while flashing custom roms. I tried 3 roms over here, namely the chocolate eclair, froyo sense extended and RCMix22B WWE.
For all of these 3, I could no longer access the 3G/HSDPA network. Anyone faced such issues or have any idea to fix it?
I tried *#*#4636#*#* and put WCDMA preferred but still unable to get through the ping test. Did a nandroid restore and 3G is working again.
Hope I can resolve this
What network you on? Custom rom developers can't possibly hope to put every apn across the globe in their roms, so you may need to enter it manually.
oh >.< didn't know that >.<
I am currently on Starhub Singapore. Will search for the apn! thanks alot for the heads up!!

[Q] Error while searching for networks

Hi guys, this really makes me crazy and I'm not able to find a solution for this problem. I've tried to search a lot on various forums but without success. I like MIUI based roms but I facing a problem with manual selection of network operators. This just doesn't work and everytime I try to search for a operator I get a "error while searching for networks" error and I can not manually select the network. I've noticed this happen on all 2.x MIUI roms with FXP based kernel. With roms based on stock kernel everything works OK. Does anybody have an idea what's the problem here and how to fix it ? I'm not sure if this is rom or kernel based issue.
My current os:
Baseband: 2.1.71
Kernel: 2.6.29-zdzihu-mod4.05
Rom: MIUI-2.3.2_Cobrato (Android 2.3.7)
Any help appreciated!
Dial *#*#4636#*#* and go to phone information, wcdma prefered, turn on radio button and check apn settings.
It may also be your SIM card. Try it in another phone. May be broken.

Hi, thanks for reply. I'm affraid problem is not in the phone nor simcard as on stock firmware this works fine. Also I'm able to register into a network as strongest network is selected automatically but I'cant select the network manually after pressing the search network button. So I can use the phone, I just can't tell the phone to select network manually. So this is annoying especially if you live on borders with another country or in roming since you are note able to select your preffered network. I mean if you go to Settings ---> Mobile network settings ---> Network operators ---> Search for networks. If you click on it, you should get the error.

Hey mizuuu & bzene, sorry to persist, just to discard operators company side by troubleshooting, did you try introducing another SIM of the same company to check if the issue remains from operator company side or OS side?
Repeat, just to discard big point of view about troubleshooting

I have an Xperia GO and have the same problem with the MIUI for Sony Xperia Go bassed on CM9 FXP and with the CM9 FXP205.
The latest roms than I have tested are :
Unofficial_MIUI_LOTUS_1359919519.zip and
FXP205-cm-9-20130201-UNOFFICIAL-lotus.zip
5020T
I've got an Alcatel 5020T which has the same problem, unfortunately I cannot find the stock or AOSP ROM for it, so I am stuck with MIUI. I've messed around with the Engineering Mode settings royally messing those up as well in efforts to reset it. This is a daily phone and I do not have another at my disposal at present so it would be VERY helpful if anyone can help.
I've installed ClockworkMod, and running Miui_Alcatel-OT5020E_4.4.4 with the 4.5.23 update. AT one point it did work at the beginning but I believe since the Engineering mode settings are below rom level they have stuck and are sticking every time I am resetting the ROM to 4.4.4 and 4.5.3 and the original port 4.3.28.
I would like to build AOSP or Cyan for it, but I do not currently have access to a Ubuntu or linux computer to do so.
Asking for one (or more) of the following from anyone:
1) Stock or any other rom for the 5020T (any of the 5020W 5020D 5020E roms should work, or are close enough I'd try them)
2) Default settings for everything in the engineering mode for the 5020 under the "Telephony" tab
3) A guide to somehow magically reset the engineering mode settings to some sort of default which most likely does not exist.
Thank you all in advance for your support, and apologies for being a grave digger.

[Q] Help

I'm no sure if this goes here but anyway, since yesterday I've been trying to upload my Custom ROM from my Galaxy S3, but everytime i change it the connectivity (2G/3G) doesn't works but the rest is ok. I've been on Omega Rom in android 4.1.1 and in this one the Data Conectivity works, but when I tried with the new versions of Omega Rom and Carbon Rom, 2G/3G just dissapear, and I don't know why this is happening . I hope someone can help me, or is it a problem from Android 4.2.2 ? PS: I can write in any of those official threads of the Roms because it doesn't allow me. Thanks so much
In setting on network pages find these
Mobile data = on
Network mode = auto
Make sure use 2g is disabled

I had the exact same experience with my wife's phone that I bought of ebay. I even flashed a variety of RIL's (radio interface layers) and different modems. I'd never had the problem with my SGS3 before, and have hundred of different roms on it.
Anyway it seemed to be a kernel issue and after trying ever combination possible I found that wifi would always work perfectly on any stock based rom or any CM based rom (assuming that hey used the CM kernel). It wouldn't even work on a CM rom if I flashed a different kernel such as Yank's, Boeffla or Googy.
Also at the time I trawled the net looking for answers and found one or two others that had the same issue, but could still use stock Sammy or CM. Strange... almost felt like it was an odd batch.

Custom ROM that has manual network selection

I hope im asking in good place. Ive tried several custom ROMs and not any has manual network selection working, always automatic selection. PE9, PE10, LOS16, different buikds tried.....not working on any of them.
Its huge problem for me where i live so any advice is well apreciated Im currently on latest PE10 and very happy with it....just this problem following me on every ROM i tried, and i really dont want to switch back to stock MIUI, i will flash xiaomi.eu ROM when i catch time, but im not too big fan of MIUi, so id rather stick to clean android experience
